So many old reels go bad. I paid for a Mort Sahl interview from the 60s, and they refunded me the money because they couldn't digitize it. Fires at Universal Studios destroyed masters of Billie Holiday and many more, and they've had multiple fires, or they get wet or wear out sitting in a college. 99% of libraries in the US will digitize your old reels and tapes. I'm always looking for rare stuff from way back, and I've received a lot of free stuff (nothing by Bukowski) from Universities simply by e-mailing their Archives department. Sometimes I'll write to all the e-mail addresses, and someone sometimes goes that extra mile.. Sometimes I'll re-ask with a different e-mail and they'll upload old audio/video for you to download. when they wouldn't months ago. Sometimes things change, especially if they get a few requests... When they do charge, it's usually $30-$50, and if you know enough fans, everyone can pitch in.
